London Wall

London Wall is a road in the City of London and a former Roman defensive wall which had been built to defend Londinium during the era of Roman Britain. It was built in approximately 200 AD, eight years after the city's fort was built, and it was developed until the end of the 4th century AD with the goal of protecting the city from Saxon pirates. It was among the last Roman building projects before the Roman evacuation of the British Isles in 410 AD, and its gates included Ludgate, Newgate, Cripplegate, Bishopsgate, Aldgate, Aldersgate, and Moorgate. By 680, London had become an important Anglo-Saxon city, but the walls were left in a state of disrepair, and the city was sacked by Vikings in 851 and 886. The city walls were repaired as the city grew, and, in 994, a Viking army sent to plunder London was repulsed. During the Middle Ages, the size and importance of London led to the redevelopment of the city's defenses. However, the city's expansion led to the abandonment of redeveloping the city walls, and the seven gates were demolished from 1760 to 1767. By the end of the 19th century, only a few remnants of the wall survived.
